Random 4 digits numeric from Formatter by Zapier

I recently got a response from the Airtable team that we may get back the random number from Formatter by Zapier.
Here is the idea
I want to have a random unique combination of four digits, the “0” ( or “00”, “000”) can not be in the beginning, I need some excellent folks to help, because now seems really possible that I’ve been trying to understand this Formatter to convert data into a different format.
Let’s try to make this happen.

@Xing did you have any luck with this?
